我點擊Click Me!顯示#formcontainer div。點擊隱藏容器div

我再次點擊它來隱藏它,但它並不能掩蓋:-(

有人能解釋爲什麼

演示:https://jsfiddle.net/v809wxp9/

jQuery(document).ready(function($) { 
 

 
    // Control Banner toggle on sub pages 
 
    $('#sub-page-banner .tog').click(function() {

你只是刪除在click.Then else語句的時候類類添加$('#formcontainer').addClass('hassent');。其回到與原來的位置。

jQuery(document).ready(function($) { 
 

 
     // Control Banner toggle on sub pages 
 
     $('#sub-page-banner .tog').click(function(){ 
 
      if ($("#formcontainer").hasClass("hassent")) { 
 
       $('#formcontainer').removeClass('hassent'); 
 
       $('#topimage').slideDown(); 
 
       $('#formcontainer').css('height', '0'); 
 
      }else{ 
 
       $('#formcontainer').addClass('hassent'); 
 
       $('#topimage').slideUp(); 
 
       $('#formcontainer').css('height', 'auto'); 
 
      } 
 
     }); 
 

 
    });

剛剛殺青OP的代碼並不是一個很好的答案。試着解釋或詳細說明他做錯了什麼,以及你改進或糾正了什麼。 – Rimble

當類缺失時,您不會將類添加回來。

jQuery(document).ready(function($) { 
 

 
    // Control Banner toggle on sub pages 
 
    $('#sub-page-banner .tog').click(function() { 
 
    if ($("#formcontainer").hasClass("hassent")) { 
 
     $('#formcontainer').removeClass('hassent'); 
 
     $('#topimage').slideDown(); 
 
     $('#formcontainer').css('height', '0'); 
 
    } else { 
 
     $('#formcontainer').addClass('hassent'); 
 
     $('#formcontainer').css('height', 'auto'); 
 
    } 
 
    }); 
 

 
});

請參見下面的代碼只需要ADDD $('#formcontainer').addClass('hassent');

jQuery(document).ready(function($) { 
 

 
    // Control Banner toggle on sub pages 
 
    $('#sub-page-banner .tog').click(function() { 
 
    if ($("#formcontainer").hasClass("hassent")) { 
 
     $('#formcontainer').removeClass('hassent'); 
 
     $('#topimage').slideDown(); 
 
     $('#formcontainer').css('height', '0'); 
 
    } else { 
 
$('#formcontainer').addClass('hassent'); 
 
     $('#formcontainer').css('height', 'auto'); 
 
    } 
 
    }); 
 

 
});

使用翻轉()函數

jQuery(document).ready(function($) { 
 

 
    // Control Banner toggle on sub pages 
 
    $('#sub-page-banner .tog').click(function() { 
 
    //if ($("#formcontainer").hasClass("hassent")) { 
 
    // $('#formcontainer').removeClass('hassent'); 
 
    // $('#topimage').slideDown(); 
 
    // $('#formcontainer').css('height', '0'); 
 
    //} else { 
 
    // $('#formcontainer').css('height', 'auto'); 
 
    // } 
 
    $('#formcontainer').toggle(); 
 
    }); 
 

 
});
/*SUb Page Banner*/ 
 

 
#sub-page-banner { 
 
    padding: 15px; 
 
    background: #3887c2; 
 
    color: #fff; 
 
    cursor: pointer; 
 
    font-size: 30px; 
 
    text-transform: uppercase; 
 
    letter-spacing: 3px; 
 
} 
 
#sub-page-banner .tog { 
 
    margin-top: 0px !important; 
 
    width: 100%; 
 
    font-size: 13px !important; 
 
    text-align: center; 
 
}

您必須添加下面的行中的其他條件:

$("#formcontainer").addClass('hassent');
